Class 0 Self Seal
The Armaflex range is the most recognised brand of
elastomeric pipe insulation, known throughout the
World. Manufactured in the UK the high quality tubes
and sheets have ODP and GWP ratings of zero and are
dust and fibre free. The Armaflex Self Seal range is
especially convenient for the insulation of domestic
central heating and cold water pipes.
Typical system applications
To supply the home with heating and hot and cold
water, pipes run through floors, walls, ceilings and
loft spaces. These pipes can lose up to 80% of their
heat en-route and transmit annoying operating noises
into the building, problems which can be mitigated by
installing Armaflex.
ARMAFLEX SELF sEAL Product RANGE
•AF/Armaflex Class O Self Seal 2m length tubes
are available in 9, 13, 19 and 25 mm wall thicknesses up to 89mm pipe diameter sizes
Pipe insulation reduces these energy losses whilst
also dampening the transmission of nuisance noise
from pipework and preventing condensation on cold
water pipes.
= cold water pipes
= domestic hot water pipes
= heating system pipes
= waste water pipes
The energy and frost protection calculation examples given on the front page are based on the following conditions:
*Save up to £75 per annum based on 80m of 22mm diameter central heating pipework, insulated with 25mm thick AF/Armaflex
Class O, at ambient room temperature of 20°C, line temperature of 70°C, boiler efficiency of 85%, operating for 5 hours a day, 280
days per year with a gas unit price of £0.05 per kWh.
**8 hours frost protection based on initial water temperature of 7°C

Your benefit:
AF/ARMAFLEX CLASS O SELF SEAL: Speed up your installation and save up to 30% on labour costs
AF/Armaflex Class O Self Seal is a nitrile rubber pipe insulation product fully slit along each length with two strips of double
sided self adhesive tape pre-applied to each open slit surface. Specially developed to provide insulation where fast, secure
installation is required and ideal for applications where working space is restricted, AF/Armaflex Class O Self Seal is easily
applied by fitting the insulation and peeling back the self adhesive tape. Fast and secure gluing of seams over the entire
length of an installation is ensured, giving a professional finish and aesthetic appearance to the entire installation.

Installation hints
ca 20 cm
A
B
Clean all dust, dirt, oil and water from pipework using Armaflex Cleaner where necessary. Install Armaflex when
ambient temperature is between +10 and +35°C. Open
the pre-slit tube and fit over the pipe. Adjust to ensure
the self-adhesive strips are easily accessible. Remove
the white protection paper strips on both sides. Close
the slit seam and squeeze together with firm pressure,
to ensure a permanent seal. The Armaflex can be pushed around long radius bends. Alternatively two piece
elbows can be formed using the cutting template printed on all Armaflex boxes and seal using Armaflex 520
Adhesive* (always cut along the flat side of tubes). The
use of a sharp ceramic cutting knife is recommended
(Armaflex Cleaner available for cleaning adhesive
from tools and Armaflex insulation). Seal all butt joints
with Armaflex 520 Adhesive. Alternatively AF/Armaflex Class O tape can be used to seal joints on central
heating pipework (not suitable to seal joins on cold
applications).
*Optimal evaporation time under normal conditions: 1 min. 30 sec.
All data and technical information are based on results achieved under typical application conditions. Recipients of this information should, in their own interest and responsibility, clarify with us whether or not
the data and information apply to the intended application area. Installation instructions are available in our Armaflex installation manual. Please consult Customer Services before insulating stainless steels.
Adhesive Armaflex 520 must be used to guarantee proper installation. Product not suitable for outdoor use without painting with Armafinish 99.
